The Home Office has confirmed that an asylum seeker was arrested on Sunday.
On Sunday evening, following reports in the national press, the man was arrested by Immigration Enforcement.
A Home Office spokesperson said: “The Government is committed to ending small boat crossings which undermine our border security, and restoring order to the asylum system to ensure that the rules are respected and enforced.
“The British public can be reassured that we take all steps necessary at all times to protect the nation's security, including taking action in the Border Security Bill to give the police and immigration officers stronger powers to act where anyone poses a threat.”
